Detailed Description

Abstract Base class for all diGraph Listener.

This is the virtual base class for graphs meta-listener.

A DiGraphListener will have to implement following pure methods :

• void whenNodeAdded( const void * ,gum::NodeId )
• void whenNodeDeleted( const void *,gum::NodeId )
• void whenArcAdded( const void *,gum::NodeId,gum::NodeId )
• void whenArcDeleted( const void *,gum::NodeId,gum::NodeId )

Constructor & Destructor Documentation

DiGraphListener() [1/2]

gum::DiGraphListener::DiGraphListener

(

const DiGraph *

g

)

default constructor

Parameters

g	the graph to listen to.

Warning

Note that, by the aGrUM's constructor parameter's rule, the fact that g is passed as a pointer means that g is not copied, but only referenced by the listener.

Definition at line 47 of file diGraphListener.cpp.

                                                   {
    if (!g) {
      GUM_ERROR(OperationNotAllowed, "A graph listener need a graph to listen to");
